I tried to fix this issue, but it seems that starting from version 1.21.6+, the client (GUI) now clips items within their slot boundaries. To disable this behavior, a MOD is required — neither textures nor plugins can modify this part of the rendering pipeline.
I tried resizing it, but the image always stayed confined within the small “slot” square; when you enlarge it, the excess parts simply get cut off for every item.
We probably noticed this change when every slot started being fully rendered, even if an image was drawn above it — previously, you could only see the outline when hovering over items, but now the full slot square is always visible.
Solution:
Move everything into a Chest GUI (which I believe is already the case). This way, the Chest title (header) can be modified freely.
That fermented spider eye should be removed, as it will no longer work. (The clickable, interactive part can still be handled using invisible items.)

@Dondius By the way, starting from version 1.21.4+, your custom items don’t appear because you’re using an old texture format!
You can easily update your textures using the following tool:
👉 https://github.com/BrilliantTeam/Minecraft-ResourcePack-Migrator
(From version 1.21.6, Mojang changed the rendering system — the client now prevents item textures from extending beyond the slot (small square) boundaries.
Essentially, you’ll be able to update all elements using the application; however, tutorial.png and tutorial_dont_show_again.png will still not appear, as this is a completely different issue.
In addition, it’s likely that the large images on the elements will also be clipped, so instead of covering the full screen, they will only appear within a small square area.)

so i fixed the testurepack for the cursor but how do i move the tutorial.png and tutorial_dont_show_again.png up to the title header?
ColorsASD commentedon Oct 22, 2025
Only LoneDev will be able to fix that because the plugin is not open source.

And you’re not fixing the cursor, you’re fixing the items — the models.
Old format: assets/minecraft/models/item/...
New format: assets/minecraft/items/...

I switched from 1.19.4 to 1.20.6. I’m not sure whether ViaVersion was the issue or if the built-in shaders from ItemsAdder fixed it, but everything is working fine for me now.
So: 1.20.6 server with a 1.21.8 client. Latest ViaVersion and ItemsAdder.
